Simon, in your recent reply to me, you noted that EDF=1 corresponds to a
straight line fit. Does the edf always indicate the polynomial exponent
directly? We ask because Hothorn and Everitt said "Roughly, the
complexity of a cubic spline is about the same as a polynomial of degree
one less than the degrees of freedom." Sorry we attributed the latter to
you, by the way. Will
